You poor salt in the pot then add luke warm water (essentially saline). You stand up straight, put the extended part of the pot to one of your nostrils and lean your head the direction the pot is pointing. It feels REALLY weird at first. Water rushes into one nostril and out the other. When youre done, just blow your nose and you're done. You can do this as often as every two hours. I do it about once a day now.
OK so back to the story. So I tried this stuff (before my nose was too stuffy for anything to come out) and did it a few times that day. My sore throat went completely away. Later I felt another coming (gosh dangit leave me alone!!) So I tried it. It worked. I now am an advocate of the neti pot. I have since been free of any sign of rhinosinusitis
So, me being the scientist that I am, looked PUBMED's website (the site where ALL legit scholarly articles are published). I looked up Nasal irrigation and they said that studies have shown that it is truly effective in preventing sinus infections. So anyone like me that gets these stinkin things should get a neti pot.
DISCLAIMER- If you cannot get any air through a nostril because it is plugged and stuffy, you've waited too long and will have to wait till both nostrils can get some air out of it. GOOD LUCK!!!
